Hello everyone Im a new owner of a 2003 w209 clk55 amg when i bought it the rear diff was shot. so i went on ebay and ordered a new one. but the one i ordered was much bigger and had a different cover (AMG cover) it also has a 3.06 ratio. now the listing says its for a 2005 clk55 but the axles in my car are to small for the new diff... so my question is. am i missing something??? was the diff i bought for a different amg?? could anybody tell me what diff i should be looking for??? thank you
